As we previously reported, Tyga has been spending a LOT of quality time with AnjaliRanadivé (aka Anjali World) ... who happens to be an aspiring singer. The two were seen getting off a private jet together earlier this month leading to speculation they were romantically involved.

But Anjali tells us, "We're just friends and working on music together."

We're told the two met through her manager ... and Anjali says they hit it off (in a platonic and professional way) -- and have been hitting the studio together ever since.

They've already recorded one song together which they performed at a recent Kings game (see video below.)

"I look up to him musically," Anjali says ... "and I can't wait to make even more music with Tyga in the future."
